Here is a link and some verbage from USNews article on the Navy electric drive. Looks like time is running out for a decision, according to the last comments.
For the Navy, an engine of change
A debate begins over new electric motors
By Richard J. Newman
They now have E-mail and gourmet coffee, and some are fueled by nuclear reactors. But in many ways, Navy ships have barely changed since World War II. They still require legions of sailors turning wrenches in steamy engine rooms. Propellers and rudders are largely the same as they were 50 years ago. Modern weapons still sling projectiles like they did in the heyday of the battleship.
Finally, that may change. U.S. News has learned that top Navy officials have decided that the next class of destroyer, known as DD 21, will rely on a new kind of power system that could transform ships the way the steam engine did in the mid-1800s. The technology?known as "electric drive"? will eliminate much of the machinery of mechanical drive systems. Shipbuilders could then design hulls that are stealthier, smaller, and more rugged. And electric drive could clear the way for laser weapons and other systems requiring huge bursts of electricity. "This represents a very dramatic opportunity," says Navy Secretary Richard Danzig....
..But some doubt that the Navy, which has about six months to decide what kind of electric drive to incorporate into DD 21, will go far enough. Low cost is a top priority for the destroyer?due to be delivered by 2008?which could leave little room for tinkering with technology....
